| Résumé : |
The applicability of the CCM technique to a fur-dyeing process was investigated.
The reflectance of dyed fur was measured by using a glass plate to prevent fur hairs entering an integrating sphere.
The reproducibility in reflectance of dyed fur was good when a glass plate was employed and the sphere was not equipped with a light trap.
The reflectance obtained by using a glass plate is considered to be different from the true reflectance, die to the influences of the reflection and transmission of light at the plate. An apparent reflectance (Rg) is defined to be the reflectance measured with a glass plate. The apparent and true (R) reflectances were correlated by the following equation.
R = (Rg-K)/(T²+KRg-K²)
Where K : Reflectance of glass
T : Transmittance of glass
0< RK<1
K/S values were determined by use of the converted reflectances and the Kubelka-Munk equation. The K/S values were correlated with the dye concentrations.
For light shades, the colors of dyed fur samples based on the calculated results were in good agreement with the color pattern to be matched. Thus, it is considered to be possible to apply the CCM technique to fur dyeing.
